UNITE PHILIP PIERRE BOLAND, OF EUREKA, MISSOURI.

COMBINED GROUND HARROW AND ROLLER.

Specification of Lettersilatent.

Patented Sept. 23, 1913.

Application filed August 28, 1912. Serial No. 717,576.

To alt whom 2'15 may concern Be it known that I, PHILIP P. BOLAND, acitizen of the United States, residing at Eureka, in the county of St.Louis and State of Missouri, have invented new and useful improvementsin Combined Ground Harrows and Rollers, of which the following is aspecification.

This invention relates to a combined ground barrow and roller, theobject of the invention being to provide an implement of this characterin which provision is made for attaching the draft appliances at eitherend of the implement, whereby the implement may be d 'awn across theground with either the barrow or the roller in advance of the other,according to the character of the work to be done, and wherein a driversseat is employed which may be reversed as to position according to thearrangement of the proper attachment.

The invention consists of the features of construction, combination andarrangement of parts hereinafter fully described and claimed, referencebeing had to the accompanying drawings, in which Figure 1 is a top planview of a combined harrow and roller embodying my invention. l ig. 2 adetail view of one of the draft bars and the draft rig removed. Fig. 3is a sectional. view illustrating the construction of the adjustableseat.

Referring to the drawing, 1 designates ground harrow of any ordinaryconstruction, and 2 a ground roller, the frames 3 and 4 of the harrowand roller being coupled by suitable pivotal connections 5, so that thetwo may be drawn together across a field with either one in advance ofthe other. The outer side of the respective frames 3 and t are providedwith similar draft bars 6, coupled thereto by fastening elements 7,which bars are adapted to interchangeably receive a draft rig orappliance 8. This draft rig or appliance is shown in the presentinstance as comprising a donbletrce 9 carrying two or more swingletrees10, said doubletree being pivotally attached to a pair of rearwardlydiverging draft rods 11 having hooked ends '12 to engage eyes 13 or thelike on the ends of either draft bar 6, by which the draft rig may becoupled to either the harrow side or roller side of the implement, sothat the implement may be drawn across the field with either the harrowor the roller moving in an advanced position, according; to thecharacter of work to be done.

The frame 4: of the roller supports a seat bar 1%1 carrying a slidingsleeve 15 adapted to be secured in position by a set screw or othersimilar fastening 16, whereby said sleeve may be adjusted in a directionlong-itlulinally of the implement. Pivot ally connected with the sleeveis a seat standard 17 carrying: a drivci"s seat 18, such pivotalconncction COI'liPllSlIlQ, a pair of toothed conpling heads 19 on thesleeve and seat standard, together with a coupling bolt 20 whereby theheads may be clamped and locked to hold the scat firmly in adjustedposition. The described constrnctimi allows the seat to be adjustedfm'wardly or rearvalfdly and to be turned to face either end of theimplement, so that the driver may have direct control over the draftanimals whether the implement is moving with its barrow portion orroller portion foremost.

From the foregoing description the con struction and mode of use of myimproved combination barrow and roller will be readily uni'lerstood, andit will be seen that the invention provides an implement of thischaracter which a'tt'ords manifohl conveniences, and by means of whichthe ground may be first burrowed and then rolled, or first rolled andthen harrowed, as circumstances may require, by the use of one and thesame ii'nplcn'ient.

I claim z A combination implement of the character described comprisinga barrow frame provided with rigid depending barrow teeth operative ineither direction of movement of said frame, said frame being providod atfront and rear with spaced eyes, a second frame having a ground rollerjournalcd therein and provided at front and rear with similarly arrangedeyes, links connecting the eyes at the inner sides of the frames, draftbars at the outer sides of the frames having; correspondingly arrangedeyes at their inner sides and each provided with a pair of spaced eyesat its outer side, links connecting the eyes of the draft bars with theeyes at the outer sides of the respective frames, a draft attachmentinclud- In testi1n0n whereof I aflix my signature ing rods having hooksadapted for interin presence 0 tWo Witnesses.
